Dolores Fuller claiming not to know what 'Glen or Glenda' was about

She says this here and in another Ed Wood documentary as well that she didn't know about Ed's cross-dressing or what Glen or Glenda was about. I find that hard to believe because they have scenes together in that movie where Ed is wearing a dress and a wig. How could she not know. What could she possibly think the film was about. That's strange and suspicious.
